Emergency fund: how much to set aside, where to keep it and how to build it
How much an emergency fund should hold, where to keep it, how long it takes to build and what it is for, with a worked example and a guide by situation.
In short
- An emergency fund is money kept aside for unexpected costs or a loss of income, not for investing or spending.
- A common rule of thumb is three to six months of essential expenses, more if your income is irregular or you have dependants.
- Keep it easy to reach and not exposed to market falls, and build it before you invest.
What is an emergency fund?
An emergency fund is a cash reserve for things you cannot plan: a job loss, a medical bill, a car or home repair, a family emergency. Its job is to stop a shock from forcing you to borrow at a high cost or sell investments at the wrong moment. It is not a savings goal for a holiday and not part of your investment portfolio.
How much should an emergency fund hold?
The most common rule of thumb is to cover three to six months of essential expenses: rent or mortgage, utilities, food, transport, insurance, debt repayments and other costs you cannot skip. It is a starting point, not a law. The right amount depends on how stable your income is and how much others depend on you.
| Your situation | Months of essential expenses to consider |
|---|---|
| Stable job, two incomes in the household, no dependants | Around 3 |
| Single income, or a mortgage and fixed costs | Around 6 |
| Freelancer, self-employed or irregular income | 6 or more |
| Children or other dependants | 6 or more |
| No regular income, for example in retirement | A longer reserve, often one year or more |
A worked example
Suppose your essential expenses are 1,500 € a month. The target changes with the months you choose, and so does the time to reach it if you set aside a fixed amount each month (ignoring interest):
| Target | Amount | At 150 € a month | At 250 € a month | At 400 € a month |
|---|---|---|---|---|
| 3 months | 4,500 € | 30 months | 18 months | about 12 months |
| 6 months | 9,000 € | 60 months | 36 months | about 23 months |
| 12 months | 18,000 € | 120 months | 72 months | 45 months |
You do not have to wait for the full target to benefit. A first buffer of one month already helps with small shocks.
Where should you keep an emergency fund?
Three questions decide it: can I reach it quickly, is it safe from losses and is it separate from my daily money?
| Option | Access | Watch out for |
|---|---|---|
| Current account | Immediate | It is easy to spend by mistake, and the interest is usually low |
| Instant-access savings account | Immediate or short notice | Variable rates and promotions that end |
| Short fixed-term deposit with early exit | Depends on the terms | Penalties or lost interest if you leave early |
| Money-market fund | Within days | Not a bank deposit and not guaranteed |
| Shares, ETFs, crypto | Quick, but the price varies | They can fall exactly when you need the money |
In the EU, bank deposits are covered by a guarantee up to 100,000 € per depositor per bank. Interest is taxed and rates vary, so compare the options: see which accounts pay interest on your savings. This is general information, not a recommendation.
How do you build it step by step?
- Add up your essential expenses for a typical month, from your bank statements.
- Choose a target in months, using the table above.
- Open a separate account so the money is visible and not mixed with daily spending.
- Automate a transfer right after you are paid, even a small one.
- Add windfalls such as a bonus or a tax refund.
- Refill it after you use it, and review the target when your costs or situation change.
What counts as an emergency?
- Yes: job loss, an unplanned medical cost, an urgent repair of your home or car, an unexpected family emergency.
- No: a sale, a holiday, a gadget or an investment opportunity. If you tap the fund for these, it will not be there when you need it.
Emergency fund or investing first?
A sensible order is usually: a small buffer, then paying off expensive debt, then a full emergency fund, then regular investing. Investing money you might need soon exposes you to the risk of selling after a fall. When the fund is in place, you can think about long-term plans such as a 20-year FIRE plan or the FIRE philosophy, and you can test how regular savings grow with the compound interest calculator. These are general considerations, not personal advice.
Frequently asked questions
How much should I have in an emergency fund?
A common rule of thumb is three to six months of essential expenses, and more if your income is irregular or you have dependants. Start with one month and build up.
Where is the best place to keep an emergency fund?
There is no single best place, but the money should be quick to access and not exposed to market falls: usually a current account or an instant-access savings account. Compare the terms and the protection that applies.
Should I invest my emergency fund?
Generally not. Investments can fall exactly when you need the money, so the fund is usually kept separate from your investments.
Should I pay off debt or build the fund first?
A small buffer first, so that a shock does not force more debt, then expensive debt, then the full fund. It depends on the interest rate on your debt and on your situation.
Does the emergency fund have to be in euros?
It is simpler if it is in the currency of your expenses, so that exchange-rate moves do not change what you can cover.
How long does it take to build an emergency fund?
It depends on your target and monthly amount: for example, 4,500 € at 250 € a month takes 18 months, ignoring interest.
